As a result, the separation of the instrument during radicular preparation can be prevented. Maintaining the integrity of natural dentition is essential for fully functional mushaps esthetic conditions.

Further, it may also facilitate the regeneration of the periodontal ligament. The presence of a separate RE in the first mandibular molar is associated with certain ethnic groups.

The presence of RE was evident on the working length radiograph [ Figure 4 ]. MTA was first described in the dental literature in and was given approval for endodontic use by the U. Scand J Dent res. An ultrasonic generator should provide a broad range of power, precise adjustment within the lower settings and electrical feedback to regulate amplitude and safe tip movement.
